The Safety Analyst is responsible for performing and ensuring the correctness of Safety analyses for a defined projectas well the support resolution of system design weaknesses’ and influencing product architecture improvements.
POSITION SUMMARY:
The Safety Analyst is responsible for the Safety analyst leading and evaluating the technical risk management assessment (FMEA/FMEDA/FTA/DFA) of the architectures by support of the technical team and operating the tools.The aim is to examine potential product or process failures, to evaluate risk priorities, and to help determine remedial actions to avoid identified problems. These work products are mandatory elements for the safety case according functional safety.
ESSENTIAL FUNCTIONS: (Individual tasks, duties, and responsibilities)
Performs FMEA (Sy, Hw and Me)
Analyzes the system components and the interactions over the interfaces
Evaluate the signal flows within the system architecture
Evaluate the static and agile behavior of the components with influence on the system
Checks the safety architecture concerning error reaction and ensures traceability to Technical safety concept and system architecture
Analyzes the influence of system resources e.g. error reaction within SW compared to the system reaction
Estimates risks of system failure modes based on the parameters severity, occurrence, detection (RPN)
Performs System (qualitative) and Hw (quantitative) FTA
Ensures verification of the System Architecture with a Fault Tree Analysis on system level.
Defines and tracks measures which will lead to an optimization of the Risk Priority Number, e.g. Adapt the System Requirements and System Architecture, e.g. concerning to the signal flow, safety concept, system status, fault management and system resources
Defines additional tests e.g. in production
Tracks the implementation of the defined measures
Performs common reviews for the System FMEA / FTA with the customer and performs con
